A proposed mathematical model to improve workforce scheduling at maintenance department of rabigh independent power plant

Abstract EN

In power producing industries, the maintenance is a crucial part to keep the availability and reliability of plant’s system at optimum level.

The optimum utilization of maintenance resources such as workforce, material and equipment are a key process to achieve organization’s profit goals.

This paper studies the maintenance workforce scheduling at Rabigh Independent Power Plant in Saudi Arabia.

It is aimed at determining optimum workforce schedules to limit the increasing demand for overtime during 5 working days of the week and 2 days of weekend and ultimately reducing the cost of workers’ overtime by utilizing the available worktime within minimum requirements.

A mathematical programming model is proposed for scheduling workforce with a scenario of two consecutive days off per week.

This model is applied for mechanical maintenance workforce with 25 % and 67 % reductions of the yearly pay hours cost and overtime cost, respectively, compared with the existing scheduling workforce scenario.
